COMBINED HARMONIUM A'ND PIANO.

SPECIFICATIQN forming part of Letters Patent No. 308,415, dated November25, 1884.

Application filed January 2'72, 1883. (No model.) Patented in GermanyJune 15, 1882, No. 20,837.

To all whom it may concern.-

Be it known that I, LEONARD Kiis'rwnn, a resident of the city ofHamburg, in the Empire of Germany, have invented certain new and usefulImprovements in Combined Harmoniums and Pianos, (for which I haveobtained a patent in Germany, No. 20,837, hearing date June 15, 1882,)of which the following is a specification.

My invention relates to improvements in harmoniums which are soconstructed that the same can be connected to any piano in such mannerthat the manuals or keyboards can. be coupled to each other at will, orbe employed separately, as shown in the accompanying drawings.

Figure 1 is a front view of the harmonium connected to a piano,- Fig. 2,a vertical section through the same, on the lines 1 2 8 4; Fig. 3, a topView of the harmonium and piano as they appear after the removal of thepiano-cover. Fig. 4 is a vertical section showing the piano-manualcoupled to the har monium-manual on the same plane and from the sameend, as shown in Fig. 2. Fig. 5 rep resents a rear view of a part of thecoupling mechanism and its connection with the rail 9. Fig. 6 is avertical section representing the coupling seen from the opposite end tothat in Fig. 4, and showing the connection of the harmonium-key with thecoupling, and showing, also, the coupling released. Figs. 7 and 8 aredetails.

Similar letters refer to similar parts throughout the several views.

The lower part of my said harmonium consists of the case or chest 13with the laterallyprojecting compartments A A. in which two bellows arearranged, which said bellows are operated by means of the pedals a a.Both bellows are in connection with the collecting 0r accumulatorbellows or wind-chest h, which is arranged in the rear space of the saidcase B. This bellows or wind-chest h is expanded by the air fed to thesame by the side bellows, a a, and feeds the air so received through thetube or pipe 0 to the reeds arranged in the reed-chest O.

In order to be able to employ the forte-pedal of the piano in treadingthe harmoniumpedals, the same is provided with a projee tion, (1, whichcan be operated by the heelof the player, whereas the pedal a isoperated by the front part of the foot. The manual or keyboard of theharmonium is arranged above the manual or key-board of the piano and iscoupled to the same in the following manner. The two stops 0 areconnected to the levers e, which carry the bar a by means of their twoarms located beneath their fulcrum e, which said bar extends from oneside of the harmonium key-board to the other. "his said bar a isprovided with perforations or holes in like number with the keys in themanual or keyboard of the harmonium to receive suitable jacks or hoppers0, one of which runs through each perforation in the bar a". Each jackor hopper, 0, is hinged to the rear arm of the harmonium key-lever 0Fig. 7, and connects the key of the harmonium manual or key-board to thecorresponding key of the piano-forte key-board in such manner that assoon as a key of the pianoforte is pressed down the rear arm of thekeylever f to the rear of the fulcrum f comes under the jack or hoppcrc"and raises the said hopper or jack 0", and also the rear end of thecorresponding lover, a, of the harmonium manual or keyboard, so that thesame effect is obtained as if the key to the harmonium-man ual had beensimultaneously depressed. If the harmonium-keys are to be uncoupled, thestop 0(id est, either the right or left stop or both) is pressed back,so that the lever c occupies the position shown in Figs. 2 and 7, andthe jack or hopper c is brought by means of the bar 0 over the cavityrecess or openingf of the key-leverf of the piano-forte key-board. Inorder to compensate for any difference in the distance of the twokey-boards, the lower ends of the hoppers or jacks e are connected tothe upper ends by means of screws. These said screws can be eitherstraight or cranked, Figs. 7 and 8, according to the position of thepiano key-board lovers in respect to those of the harmonium-manuallocated above the said piano-forte key-board. The case or chest B, withthe compartments A A, is simply pushed on the lower part of the piano,whereas the upper part of the harmo nium rests with it, supporting rodor board 9 in two checks or guides, b, screwed to the sides of theframe-work of the piano.

Having now described my said invention and the manner in which the sameis to or vcrs 0, rod 0", and the jacks or hoppers e, 10 may becarriedinto effect, WhatIclaim as new substantially as described in theforegoing and novel, and desire to securcbyLet-tcrs Patspecification andshown in the accompanying ent, isdrawings.
